In one What's New episode they try something different and have Fred and Shaggy pair up when it's time to split up. It gets awkward.
Fred: So... did you see the game last night?
Shaggy: Uh, I'm not really into sports.
Fred: Oh, right...
Shaggy: Wanna go get something to eat?
Fred: No thanks, I'm not hungry.
Fred: From now on let's split up like we normally do.
